A classic model using the equations is of the population dynamics of the lynx and the snowshoe hare, popularised due to the extensive data collected on the relative populations of the two species by the Hudson Bay company during the 19th century.

 VOLTERRA
Vito Volterra, an Italian mathematician, was born in Ancona in 1860 and died in Rome in 1940.
In his last years Volterra was also interested in biometrics, and developed (1927) A. Lotka's theories, trying to express the mutual actions of associated biologic species under the shape of differential equations and to deduce the behaviour of fluctuations of biologic populations.
Volterra showed the possibility of applying exact and strict methods to the universe of human sciences, attributing a theoretic centrality to mathematics in relation with philosophy studies.

Volterra was born in Ancona and studied at Florence and Pisa.
Volterra contributed especially to the foundation of the theory of functionals, the solution of integral equations with variable limits, and the integration of hyperbolic partial differential equations.
Volterra's main works are The Theory of Permutable Functions (1915) and The Theory of Functionals and of Integral and Integro-differential Equations (1930).

 Volterra Series - Wikipedia, the free encyclopedia
Beginning in 1887 it was developed by Vito Volterra in analogy to the Taylor Series for functions.
The theory of Volterra Series can be viewed from two different perspectives: either one considers an operator mapping between two real or complex function spaces or a functional mapping from a real (complex) function space into the real (complex) numbers.
Hence, estimation of Volterra coefficients is generally performed by estimating the coefficients of an orthogonalized series, e.g.

Vito Volterra (May 3, 1860 - October 11, 1940) was an Italian mathematician and physicist, best known for his contributions to mathematical biology.
Born in Ancona, then part of the Papal States, into a very poor famiily, Volterra showed early promise in mathematics before attending the University ofPisa, where he fell under the influence of Enrico Betti, and where he became professor of rational mechanics in 1883.
Volterra had grown up during the final stages of the Risorgimento when the Papal States were finally annexed by Italy and, like his mentor Betti, he was an enthusiastic patriot, being elected as a senator of the Kingdom of Italy in 1905.

 Lotka-Volterra equation - Wikipedia, the free encyclopedia
The Lotka-Volterra equations, also known as the predator-prey equations, are a pair of first order, non-linear, differential equations frequently used to describe the dynamics of biological systems in which two species interact, one a predator and one its prey.
They were proposed independently by Alfred J. Lotka in 1925 and Vito Volterra in 1926.

A Volterra la storia ha lasciato il suo segno con continuità dal periodo etrusco fino all’ottocento, con testimonianze artistiche e monumentali di grandissimo rilievo, che possono essere ammirate semplicemente passeggiando per le vie del centro storico, ma anche visitando i tre musei cittadini: il Museo Etrusco, la Pinacoteca Civica e il Museo d’Arte Sacra.

Vito Volterra was an Italian mathematician and physicist, best known for his contributions to mathematical biology.
In the same year, he began to develop the theory of dislocations in crystals that was later to become important in the understanding of the behaviour of ductile materials.
He was compelled to resign his university post and membership of scientific academies, and, during the following years, he lived largely abroad, returning to Rome just before his death.

 Predator-Prey, Part 2
Vito Volterra (1860-1940) was a famous Italian mathematician who retired from a distinguished career in pure mathematics in the early 1920s.
He concluded that the predator-prey balance was at its natural state during the war, and that intense fishing before and after the war disturbed this natural balance -- to the detriment of predators.
Having no biological or ecological explanation for this phenomenon, D'Ancona asked Volterra if he could come up with a mathematical model that might explain what was going on.

 PREDATOR
Since we are have two interacting species, the model requires two linked differential equations, the first which describes how the prey population changes and the second which describes how the predator population changes.
Vito Volterra used a system of differential equations to explain the variations in the shark and food-fish populations in the Adriatic sea.
One of the first models to incorporate interactions between two speciea, predators and prey, was proposed in 1925 by the American biophysicist Alfred Lotka and the Italian mathematician Vito Volterra.

Arguably, the most complete formulation on the problem of “The Struggle for Existence” (G. Gause, 1934) was published by Vito Volterra in Paris in 1931, under the title: Leçons sur la theorie mathematique de la lutte pour la vie.
Although much work has been done during the intervening years, Volterra’s quantification of the growth and recession of populations in conflict (“the prey and the predator”) remains the definitive work on the subject.
Although Volterra’s original equations have defied exact solution in their most general form, BEE mathematicians have applied modern computational methods to their numerical solution.

In 1881, Vito Volterra, then a 21 year old student at the Scuola Normale Superiore di Pisa, proved that there could be no function on R which was continuous at every rational number and discontinuous at every irrational number.
Volterra's elegant proof will be presented (it pre-dates Baire's proof by a generation and uses only elementary analytic tools), but we will also look at the historical background which led to interest in such pathological functions.
Students who have completed Calculus II will be able to follow much of the talk, and will enjoy a lot of the history.
